Application filed February 10, 1927; Serial No. 167,175.

The invention relates to track construction and more particularly to track con-V struction for use in connection with motordriven vehicles.

lVhere trucks carrying heavy loads are used on soft ground as, for instance, in concrete highway construction where supply trucks for bringing the aggregate to the mixer have to pass over the subgrade to deposit their loads either into the loading skip of the mixer or adjacent thereto. this subgrade, because of the weight of the trucks and the frequent damp or muddy condition of the soil, does not provide a good foundation for the trucks and soon becomes badly rutted so that great difiiculty experienced in getting the trucks to the unloading point. The object of this invention is to provide a demountablejor sectional track construction upon which the trucks may be driven over soft ground such as above noted, wherein each line of the track consists of a plurality of track sections of angular format-ion having a flange. on the inner side of the track so that the track will taketrucks with any width of tire in the rear since part of the tire, or in case of double tires one of the tires, may project beyond the track, said track sections being secured together at their ends and spaced apart to suit the inside wheel gauge of the trucks by spacingmembers removably connectcd with the track sections.-

The invention further consists in the several features hereinafter set forth and more particularly defined by claims at the conclusion hereof.

In thedrawings Fig. 1 is aside elevation view of a portion of a sectional track embodying. the invention;

Fig. 2 is a plan view thereof, parts being broken away;

Fig. 3 is a perspective end view of one of the track sections associated with a' spac ing member;

Fig. 1 is a section taken on the line 41 of Fig. 2; I

Fig. 5 is a detail sectional view taken on the line 5-5 of Fig. 2.

In the drawings the numeral 7 designates the vtrack sections. tions is preferably formed of sheet metal, such as heavy boiler iron, which is stamped or otherwise suitably formed into angle sec tions having a base ortion 8 and an inner side portion 9 provided with a laterally Each of these track secextending flange 10 and an ear 11 at each end of the track section which is welded or otherwise suitably secured to the inner side flange 9 of the track section and the crates.

flange 10 and is provided with a hole 12.

Adjoining sections of'th e track are secured in alined position by an angle bracket 13 and a clip or anglelug 14, said bracket and lug being mounted on. a support 15.

2 Each of the angle brackets 13 consists of a base portion 16, an upright portion 1'7 and a bifurcated flange portion 18 with'avertically disposed s10: 19 between the bifurcations and extending down into the upright portion 17.

The angle lug 14 engages over the'outer sides of the adjoining 'tracksections and is spaced from angle bracket 13 to accommodate the width of each track section 'disposed therebetween. On one side of the track the bracket 13 and lug 1t may be fixedly secured to the support 15 in any suit able manner, as by rivets 19a On the other side of the track, in order to adj Listthe track to trucks of different wheelgauges, it is preferred to secure the angle bracket 13 and the lug 14 in spaced relation to each other and relative to the other side of the track by means of bolts 20 and the supports 15 are provided with a series of sets of holes. 21 to permit of-this adjustment.

lVhile the supports 15 perform the don ble function of acting as a tie between track sections on each side of the track and'as a spacing means for the track sections, it will be understood that separate bars similar to the supports 15 can be used to space the sides of the'track apart without departing from this invention. Furthermore, it will be understood that the supports 15 are not load supports for the track as they have a relatively'small bearing area and the weight of the truck is taken by the track sections themselves, the width of the channel being sutlicient to take the load. j

The adjoining track sections are secured together by the interfitting relation of the side portions of each section with the bracket 13 and lug 14;, the disposition of the ears 11 against the inner sides of the bifurcations 18 and by pins 22 or other suitable fastening means which pass through the holes 12 in the ears of the adjoining track sections and preferably have a clamping engagement with the under side of the bifurcations 18,

taper so to secure a good tit and to acconnnodale for possible slight inaccuracies of alinement between the adjacent track sectiona. 'lhe engagement ot the cars ll with the braeheta lZl preventa longitudinal. displacement of the track sections relative to each other and the connection oi theae sections; with the brackets 13, lugs ll and supports l5 prevents spreading oi the lines of the track relative to each other.

In arranging the device for use the spacing members or supports 15 are laid upon the euhgrade or soft soil 2? at appropriate interval-.4 and the track sections T are placed so as to bring their ends between the spaced brackets 13 and lugla l-il. with the cars it in position, and the pins are then driven into place with the resul that a track of sullicient bearing surface for the wheels 2t of a trucl' 25 is provided to enable the truck to negotiate the soft ground and deposit its load as. for instance, into the ship 22a of a mixer. Furthermore. since the track txions T have flanges on their inside portion only the track Will take trucks With any Width of tire in the rear or trucks with double tires and the track sections may be made relatively light.

While I have described the use of the track sections more particularly in connection with the soft soil of the subgrade 01? a road under construction, it will be understood that the track may be used for motor Y6l1icles on any kind of soft ground where it is necessary to prevent vehicles from becoming mired.

I desire it; to be understood that this inventiion it}; not to be limited to any particula r form or arrangement of parts except in so far as such limitations are specified in the claims.

I claim:

1. In a track construction, the combination ot a plurality of track sections. each having a base portion and an inner side flange, means for connecting adjacent ends of said track sections together to prevent- .longitndinal displaeeinei'it thereof con'ipriain; an angle lug engageable with the outer side of the base portions of adjoining track sections and an angle bracket engragtaible with said flanges of adjoining track aections, and means for preventing: lateral di.-=place ment' of said track sections.

In a track conatructioin the ('tllllbllltililtill of a plurality of track sections each having a base portion and an inner side llanggje harin; laterally extending l'lane'e portions, a pair of spaced connectors between which adjoining track sections are tiliapnsed comprising a clip engageable with the outer side oi. the base portions of said seetiona. and a, bracket; l'iarine' flanges engarniable with the flanges of said track sections to prevent longitudinal movementof said track sectiona.

3. In a track cmistructziou. the combination ot' a plurality of track sections, each having a base portion and an inner side llangre, a support, spaced eomiectors mounted on said support engageable respectively with the base portions and the flanges of adjoinin; track sections, and means engragreable with the connectors of said. flanges and an id flanges for holding said sections in alinement.

-:l-. In a track construction, the combination of a pluralitq, of track sections, each baring a, base portion and an inner side flange a spacing member, spaced. sets of corn neetors mounted on said spacing membcuf for adjustmentrelative to each other, each set of connectors having a connector engage able with the base portions: of adjoining; acetions and a connector engageable with the flanges of adjoining track sections.

5. In a track constructiol'i, the combination of a plurality of track sections, each having a base portion and an inner side flange provided with a laterally extending apertured ear at each end, a support. a clip mounted on said Support and titling over the bane portions o'l. adjoining; sections at the outer aides thereof. and a bracket; mounted on said. support and having; a llange portion engageable with the ears ojt adjoining; sections, and means extending through the openings in said ears and engaging said bracket.

In testilnonv whereof, I allix my signatin'e.
